An Improper Handling of Exceptional Conditions vulnerability in routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker executing a CLI command to cause a Denial of Service (DoS).
When asregex-optimized is configured and a specific "show route as-path" CLI command is executed, the rpd crashes and restarts. Repeated execution of this command will cause a sustained DoS condition.
This issue affects Junos OS:
* All versions before 21.2R3-S9,
* from 21.4 before 21.4R3-S10,
* from 22.2 before 22.2R3-S6,
